Some of the most responsive ads I've ever written have been those where I told a simple story in my ad. I told of a problem I had and then proceeded to tell the reader how I solved the problem with a product or service I was selling.
First hand experience is a good selling point. I don't just make up a story. I tell about my own personal experience and how my problem was solved with the product or service I'm promoting.
Think about this for a minute...why do you always see "weight loss" commercials with before and after pictures? And usually the person who lost the weight is the one doing the talking on the commercial? Because it sells, that's why. You see first hand the weight problem the person was having, and then you see how the product solved the "weight" problem.
Hope this helps,
